Allogeneic myoblast cell sheet transplantation for esophageal wall reinforcement

Figure 3 Macroscopic findings of grafted tissue in the transplant group. A: At 1 week postoperatively, nodular thickening of the esophageal wall was observed at the site of myoblast cell sheet transplantation (△); B: At 2 weeks postoperatively, the nodules observed at week 1 had disappeared, and the transplantation site showed a smooth esophageal wall surface (△); C: At 4 weeks postoperatively, the macroscopic findings at the transplantation site remained consistent with those observed at week 2 (△).
